Description
Technical field
The present invention relates to medical instruments field more particularly to a kind of evaporated condensation water mechanical ventilation breathing pipelines.
Background technique
Common breathing circuit, since the temperature and humidity of gas in pipeline is higher than indoor temperature and humidity, causes when ventilator works
A large amount of condensed waters are generated in pipeline, are the high risk factors for leading to cause by breathing pipeline mechanical ventilation mode pneumonia.It is existing to add
There is following objective disadvantage by heater strip heating, drying condensed water in managing in heat type breathing circuit:
It is built up 1. the temperature difference that heater strip improves in pipe and outside pipe in managing causes more to condense；
2. condensed water accumulates in pipe the humidifying effect for actually reducing ventilation gas, mechanical ventilation cannot be guaranteed gas
95% or more relative humidity easily leads to respiratory airway damage；
3. a large amount of condensed waters are the environment of bacterial reproduction, and the phenomenon that condensed water flows backward respiratory tract or intrapulmonary occur.
Summary of the invention
The purpose of the present invention is to provide a kind of evaporated condensation water mechanical ventilation breathing pipelines, and solving the prior art can not be from root
Breathing pipeline condensed water is solved the problems, such as on source.
To achieve the above object, technical scheme is as follows:
A kind of evaporated condensation water mechanical ventilation breathing pipeline, including breathing pipeline, the breathing pipeline include suction line and
The outer wall of expiration pipeline, the suction line and expiration pipeline is wound with spiral heating wire, is equipped with and adds in the suction line
Thermoelectricity heated filament and temperature sensor.
Further, described suction line one end is pipeline inlet end, and the other end is breathing end connector, heats heating wire position
In pipeline inlet end side, the temperature sensor is located at breathing end connector side.
Further, the suction line and expiration pipeline are heating wire spiral pipeline.
Further, the heating heating wire is U-shaped structure.
A kind of evaporated condensation water mechanical ventilation breathing pipeline of the invention is controlled using dew-point temperature control principle and eliminates breathing
Condensation in pipeline guarantees that patient sucks the temperature and humidity of gas by breathing pipeline, to reduce the hair of ventilator-associated pneumonia
Raw rate, reduces medical expense and case fatality rate.

Specific embodiment
Technical solution of the present invention is described in further detail with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of evaporated condensation water mechanical ventilation breathing pipeline of the invention, breathing pipeline include suction line 4
With expiration pipeline 5, wherein the outer wall of suction line 4 and expiration pipeline 5 is wound with spiral heating wire 8, installation in suction line 4
There are heating heating wire 6 and temperature sensor 7.
In general, 4 one end of suction line is pipeline inlet end 1, the other end is breathing end connector 3, and heating heating wire 6 is located at pipe
1 side of road inlet end, the temperature sensor 7 are located at breathing 3 side of end connector.
In one embodiment, suction line 4 and expiration pipeline 5 are heating wire spiral pipeline, are twined convenient for spiral heating wire 8
Around；Heating heating wire 6 is U-shaped structure, is evenly heated and controls sucking gas temperature.
As shown in Fig. 2, the gas humidification controller 9 of breathing pipeline adaptation corresponding function of the invention is used and is applicable to
The ventilator of any brand.Gas humidification controller 9 includes heating wire temperature controller, and the temperature being mounted on breathing pipeline passes
Sensor 7, heating heating wire 6 and spiral heating wire 8 are by being correspondingly connected with interface and heating wire temperature control on gas humidification controller 9
Device processed is connected, the air inlet 11 and outlet that gas humidification controller 9 is equipped with humidification pot 10 and is arranged on humidification pot 10
Mouth 12, air inlet 11 connect the aspirating end of ventilator, 12 connecting line inlet end 1 of gas outlet, and pipeline expiration end 2 connects ventilator
Expiration end.The heating temperature for the temperature control heating heating wire 6 that heating wire temperature controller is detected according to temperature sensor 7,
The temperature of gas is sucked using temperature servo's control principle control user；Heating wire temperature controller is according to temperature sensor temperature
The heating temperature that spiral heating wire 8 is controlled using dew-point temperature control principle, is realized and eliminates condensation.
Breathing pipeline of the invention eliminates respiratory siphon by optimization pipeline structure and using the control of dew-point temperature control principle
It is condensed in road, guarantees that patient sucks the temperature and humidity of gas by breathing pipeline, to reduce the generation of ventilator-associated pneumonia
Rate reduces medical expense, reduces case fatality rate.
Above-described specific embodiment has carried out further the purpose of the present invention, technical scheme and beneficial effects
It is described in detail, it should be understood that the foregoing is merely a specific embodiment of the invention, the guarantor that is not intended to limit the present invention
Range is protected, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should all be contained in this hair
Within bright protection scope.
